The principle of fast replay in wifi
In the case of a IP connection, data is divided into packets and each packet has a sequence number. When the receiver did not receive the expected data packet, it would send a request to the sender. If the sender did not receive a confirmation from the other party within a certain period of time, the data packet would be retransmitted. The fast replay mechanism was that when the sender received three consecutive replay requests (three repeated acknowledgment messages), it would not wait for the time to expire to try again. Instead, it would immediately replay the last packet sent. In the fast replay state, the traditional way was for the sender to stop sending new packets and wait for the receiver's confirmation, but this method could cause a long network delay. The fast replay mechanism also involved the priority of the data segment transmission: 1. Priority1: A data segment marked as LOST (defined by the IsLost routine of IFC3517, which is considered LOST when certain conditions are met). 2. [Prioritization 2: New unsent data segment.] 3. [Prioritization 3: Data segments that are not marked as LOST, Sacked, or retransmitted within the range of UA and Hi.] After fast retransmissions, instead of slow start, the algorithm was used to avoid congestion (also known as fast recovery algorithm). It was designed to quickly recover lost data packets, thereby improving the transmission efficiency of the network, reducing network delay, and improving the stability of network communication.

Tccp's fast replay mechanism
The fast replay mechanism of the protocol is a part of the protocol's congestion control mechanism. It mainly relied on the serial number and acknowledgment number in the header to decide whether to re-transmit or not. The trigger of the fast replay mechanism was related to the transmission state of the data packet. In the traditional protocol, if the sender did not receive an acknowledgment from the receiver after the timer set by the sender expired, the packet would be retransmitted (this was considered a time-out). The fast re-transmission mechanism provided a faster way to trigger the re-transmission. For example, when the receiver receives an out-of-order packet, it will immediately send a duplicate acknowledgment to the sender. If the sender received a certain number of repeated AKs in a row (usually three), it would trigger the fast replay mechanism, which quickly retransmitted the data packets that seemed to have been lost without waiting for the timer to expire. NewReno is a fast replay and recovery algorithm for the IP protocol. It is suitable for IP connections that do not support the SACK option. It is designed to improve performance in the case of multiple packet losses within a single window. In general, the fast replay mechanism helped to improve the efficiency of the transmission, reduce the delay caused by waiting for a time-out before retransmitting the data packet, and better deal with problems such as packet loss in the network.

Super Wifi
Super Wi-Fi was a full-featured Wi-Fi management software that could provide one-click cooling, one-click speed up, network environment optimization, real-time viewing of network data, and other functions. In addition, the Ultra-Wi-Fi also had an automatic optimization function that could analyze and optimize the Wi-Fi signal to provide a more stable and faster network connection. It also had a Wi-Fi acceleration function, which could effectively increase the network transmission speed, allowing users to feel faster when playing games, watching high-definition videos, and downloading files. In addition, the super Wi-Fi also provided Wi-Fi security protection. For the specific usage of the Super Wi-Fi, you can download the Super Wi-Fi Universal Link app.
Is there wifi in the ICU?
According to the information provided, some hospitals installed free Wi-Fi in the waiting area for family members in the ICU, but there was no mention of whether there was Wi-Fi in the ICU ward. Since the ICU was an area that required highly specialized and concentrated care, in order to ensure the safety of patients and the confidentiality of medical records, the use of Wi-Fi networks needed to be especially cautious. Moreover, every hospital or medical institution had its own security policies and regulations, so it was impossible to determine whether there was Wi-Fi in the ICU.

Wild wireless wifi
Setting up a wireless Wi-Fi network in the wild required some specific configuration and precautions. First of all, you need to set up a wireless gateway, make sure you set up the SSID and password, and enable Wpa2 encryption. In addition, you also need to place the device in a location far away from the device but with good signal coverage. For outdoor Routers, you usually need to use PoE power supply, which means you need to pull a network cable to the location of the Routers and make it waterproof. In addition, when choosing the location of the gateway, you should avoid placing it higher than the person to avoid affecting the signal range, and pay attention to avoid the signal being blocked by other electronic devices or objects. When carrying out outdoor wireless coverage, you should also choose a wireless AP with an IP protection rating to ensure that it can still be used in extreme temperatures and harsh weather conditions. In short, by properly configuration the routers and choosing the appropriate location and equipment, you can establish a stable wireless Wi-Fi network connection in the wild.
Blowing Principle
The principle of bleachings was to make objects lose their color through the oxidisation properties of bleaches. Different types of bleaches had different principles. The principle of the bleaching-powder was that the bleaching-powder would produce hypochloric acid when it came into contact with water. The hypochloric acid could catalyze the coloring matter, thus achieving the purpose of the bleaching-powder. The principle of hydrogen dioxide was that hydrogen dioxide was a strong oxidiser. It could destroy the " chromophore " inside the organic color substance and cause it to lose its original color. The principle of the absorption bleachings was that the substance had a large surface area, which could absorb the dye and make the substance fade. Other bleaches such as sulfur dioxide and ClO2 had similar principles. In general, bleaches change the color of objects or fade them through an oxidization reaction.

Reflex principle
The principle of reflexivity was proposed by Soros. This principle was based on a phenomenon that existed in human affairs: when someone was involved in something, the participant's view of the world was one-sided and distorted (fallibility principle), and these distorted views would in turn affect the things related to the point of view. From the perspective of the connection between the participant's thinking and the situation they participated in, it could be decomposed into a cognitive function and a participation function. In the cognitive function, the participant's cognition depends on the situation; in the participation function, the situation is affected by the participant's cognition. The interaction between the two is called reflexivity, which can be expressed as a pair of recursion functions: y = f(x), x = q(y). In the field of economics, traditional theories often avoided or denied reflexivity, and Soros believed that a fundamental factor in the existence of reflexivity was human cognitive bias. In addition, Kant believed that the application of moral laws in practice was based on the principle of reflexivity. This principle meant that every moral law must become a basic principle, and every rule must conform to the basic principles that any rational person could accept. In the moral theory he constructed, he emphasized human free will and free decision. This principle was widely used in modern philosophy and promoted the development and progress of human thinking.
